1. On {IDF_TARGET_NAME}, if RTC8M_CLK is chosen as the LEDC clock source, you may see the frequency of output PWM signal is not very accurate. This is because no internal calibration is performed to get the exact frequency of the clock due to hardware limitation, a theoretic frequency value is used.
